In this paper I consider social choices under uncertainty. I prove that any social choice rule that satisfies independence of irrelevant alternatives, translation invariance, and weak anonymity is consistent with ex post Bayesian utilitarianism.

Recent developments in the econometric estimation of multi-output, multi-inp ut distance functions have provided a promising new solution to the single-output restriction implicit in the standard production function. However, a suspicion that regressor endogeneity may introduce possible sim...

In this survey we address three of the principle algebraic approaches to integer programming. After introducing lattices and basis reduction, we first survey their use in integer programming, presenting among others Lenstra's algorithm that is polynomial in fixed dimension, and the solution of...

This paper develops a posterior simulation method for a dynamic tobit model. The major obstacle rooted in such a problem lies in high dimensional integrals, induced by dependance among censored observations, in the likelihood function.
